As a member of the disease control group for COVID-19 in central China's Hubei Province, Dr. Yu Changping found himself infected late January. He has kept recording ever since, analyzing his illness every day and sharing it with the public on social media networks to encourage people with positive attitude and laughter. Today marks the 15th day of his quarantine after being discharged from the hospital. CGTN reporter Li Jingjing takes us into his quarantine room and has a chat with him.
